NFL.com reports that Harrison will have surgery on his right shoulder, "according to the player" -- but it's worth noting that Harrison mentioned nothing about what exactly he injured.

It's entirely possible the surgery is on the right shoulder -- Harrison did suffer a shoulder injury in the divisional round game against Baltimore but obviously wasn't going to undergo surgery with the Steelers still in the hunt for the Super Bowl.

Clearly, Pittburgh needed him in their run, but he wasn't as effective after the Baltimore game -- he registered seven total tackles, three sacks and a pass deflection against the Ravens and just seven tackles and one sack in the Steelers' final two games.

Given the time frame for his recovery, it's clearly not just a minor procedure, but it's also something he wants to handle immediately and not let linger; the month-and-a-half recovery time means he'll probably be prepared to start playing football before there's actually any football ready to be played.

The most gifted linebacker in Pittsburgh is not named James Harrison. And he’s not named LaMarr Woodley. Or Jam es Farrior. The most gifted linebacker in Pittsburgh – and perhaps the entire NFL – is named Lawrence Timmons.

The fourth-year pro from Florida State enjoyed a breakout campaign in 2010. Originally drafted to play outside linebacker, Timmons’ initial development was slow, if not non-existent. But he started to progress after coaches moved him inside. Despite having just average awareness in coverage, he handled nickel duties in ’08 before assuming a fulltime starting role in ’09. He had 12 sacks his first two years inside.

Because his sack total dropped to three in ’10, Timmons suggests that teammate James Farrior is actually Pittsburgh’s best inside blitzer (Farrior had six sacks). But that’s either false modesty or naivety. No player can match Timmons’ downhill explosiveness or fluid athleticism.

It’s not just blitzing and rushing the passer, either. “I feel like I should have had more sacks, but as far as stopping the run and playing in coverage, I think I did very well,” Timmons says.

DALLAS -- Had a chance to chat with Josh Freeman on Friday (he was making the media rounds as part of the Gatorade Sports Science Institute lab that is stationed upstairs from radio row). The conversation centered largely around the lessons he’s learned in his first two years in the NFL. Freeman said that facing more frequent and complex A-gap blitzes was the toughest on-field tactic that he had to learn.

The Steelers just so happen to be one of, if not THE, best fire-X blitzing team in football (fire X is an A-gap blitz in which the inside linebackers crisscross on their way to the quarterback). Freeman offered one of the shrewdest yet simplest observations that has been made this week in Dallas: the Steelers front seven is extra difficult to figure out because the linebackers mix their 90s and 50s jersey numbers.

Normally, defensive linemen are the ones who wear numbers in the 90s. But Steelers outside linebacker James Harrisons is No. 92. And inside linebacker Lawrence Timmons is No. 94. (The other starters, James Farrior and LaMarr Woodley, are 51 and 56.)

Obviously, it’s easy to tell the difference between all four Steelers linebackers. But when you’re on the field and have a million things going on, it’s a little harder. If your first point of reference is normally a jersey number, and linebackers wearing numbers in the 90s are roving around, those linebackers are going to blend in for a split second. Split seconds are a significant chunk of time in football.

If a media type or outside observer had made this point about jersey numbers, it probably wouldn’t be worth a second thought. Jersey numbers? Really? But when a quarterback who has faced the Steelers brings it up on his own, there’s something to it.

ARLINGTON, Texas – I was talking to Steelers backup QB Charlie Batch the other day at Media Day, and we were discussing the sheer number of Mid-American Conference alumni who were participating in the festivities this week and were preparing themselves to play in the Super Bowl.

“It’s pretty crazy,” I said to the man who played at Eastern Michigan more than a decade ago. “There are 13 of you guys playing.”

“Actually,” he said, “there are 15 if you count the practice squad guys.”

Well, I count 13. Batch thought there were 15. Either way, it’s an impressive total for a non-BCS conference that doesn’t get much in the way of respect from college football/pro football fans.

“Obviously, we can get our guys out there, and we take a lot of pride in it,” Zombo said. “We talk about it quite a bit in the locker room. Some of the key players from the game are from the MAC who are contributing huge for the team. It shows the caliber of player we have in the MAC conference.”

That’s one impressive aspect of this story. It’s not just the scrubs or the practice squad players. It’s guys like Roethlisberger and Jennings and Harrison and Jenkins – some of the biggest stars of the game.

“The only difference in the MAC schools and the (BCS) conferences is the budgets in the programs,” Gordy said, and he’s probably partially correct.

In fact, the MAC has more players that will compete this week than the Big 12 (eight players), Pac-10 (six) and the Big East (four). All of them are BCS conferences. All of them have less MAC players (for the record, the SEC has 18, the Big Ten has 15 and the ACC also has 13).

Still, it’s a nice boon for the MAC that it has so much representation this week.

“At that level, there’s talent everywhere,” Crabtree said. “Whether you’re in the MAC or the Big 10 or whatever, there’s talent across the board. The MAC might not have the depth other conferences have, but the talent is still there.”

The Packers’ ground game doesn’t have a prayer against a Steeler run defense that ranks third all-time in the modern era. Center Scott Wells is a cagey veteran, but he struggled all season to hold ground against vociferous nose tackles. There may not be a more punishing run-stopping nose in the game than Casey Hampton. Even if the Packers can somehow neutralize that interior mismatch (and it’s doubtful they can), James Starks, decent as he’s been this postseason, lacks the speed and agility to elude Troy Polamalu, Ryan Clark and Pittsburgh’s superb linebacking corps.

Green Bay’s best chance on Sunday will be to isolate their wideouts against the Steelers defensive backs. Don’t be surprised if the Packers spend most of the game in four wide receiver sets. That would force Dick LeBeau to play nickel or dime and keep either his leader (James Farrior) or most athletic player (Lawrence Timmons) off the field. It would also isolate at least one of Green Bay’s wideouts on one of Pittsburgh’s cornerbacks.

For Green Bay, the most attractive mismatch in the passing game will be inside. Steelers nickelback William Gay, who occasionally struggles in man coverage, will have his hands full against either James Jones or Jordy Nelson.

Also, expect the Packers to keep Greg Jennings on the right side of the formation, where he’s more likely to face Bryant McFadden. McFadden, like his counterpart Ike Taylor, is stout enough as a tackler to keep the catch-and-run happy Packer receivers from breaking a big one. But unlike Taylor, McFadden does not have great length or catch-up speed over the top. Jennings, one the crispest and most befuddling downfield route runners in the game, can exploit this.

Most importantly, spreading the field will create natural throwing alleys for Rodgers. This is critical because, with Chad Clifton going against James Harrison and Bryan Bulaga going against LaMarr Woodley, shaky pass protection will limit Rodgers to mostly three-step drops.

It will be fascinating to see whether LeBeau allows Rodgers to complete passes off three-step drops or whether he tries to counter the quick pass. Countering it likely means taking a reactionary defensive approach – something that is generally unfamiliar for LeBeau’s unit. Normally the Steelers love to blitz their inside linebackers (often this is what creates one-on-one scenarios for their potent outside linebackers). But to counter Rodgers’ quick strikes, the Steelers may drop eight into coverage and rush only three. Harrison and Woodley are both adept in space. If the linebackers are dropping back, Pittsburgh’s corners get to play zone instead of man. That helps appease the mismatch against Green Bay’s wideouts.

The X-factor, as usual, is Troy Polamalu. How LeBeau decides to utilize his most dynamic playmaker will determine whether the Steelers blitz or drop back. If Polamalu roves around the box, expect blitz. If he roves around centerfield, expect drop back.

Speaking of Polamalu, here's what LeBeau had to say about the legendary safety.

Perhaps the most fascinating thing if you look (at a glance anyway) at Pittsburgh and Green Bay is that they've built their teams "properly." (AKA "the opposite of Dan Snyder.) They draft smart, and they sign smarter. At least that's what we're lead to believe, right?

Andy and I set out to check the roster breakdown for both teams. En route, we* managed to figure out not only where they're coming from, but what they'll do for their respective teams in the Super Bowl.

Whoever's the 2nd most athletic ILB in football is barely a speck in this man’s rearview mirror. Instincts have improved precipitously. In short, he’s already a superstar (and maybe Pittsburgh’s best player on D).

Llike the Steelers have a 12 on 11 advantage when he’s out there. The difference between him and other star defenders? 2 things: his calves (which give him NBA-caliber vertical leap and incredible closing explosiveness) and unwavering trust in his instincts.

DALLAS – The buzz in the media room the last few minutes has been about the report that Clay Matthews had won the defensive player of the year award and that how … well … that report might be a tad premature.

While Matthews was fantastic early this season – there was plenty of talk that he had a chance at breaking Michael Strahan’s sack record (remember that?) – he made less of an impact as the season wore on. With only three sacks in the last seven games of the season, he finished with 13.5, two behind Dallas’ DeMarcus Ware, the league leader.

Meanwhile, Polamalu was his usual brilliant self for Pittsburgh, collecting 63 tackles in 14 games while intercepting seven passes (tied for his career-high) with 11 defended passes.

It’d be hard to ask for a better matchup in Super Bowl XLV than the Green Bay Packers vs. the Pittsburgh Steelers. These are the hottest teams in their respective conferences. Both have big-name quarterbacks, playmakers on offense and a host of Pro Bowl caliber contributors in their well-coached 3-4 defenses. It’s no wonder the oddsmakers and pundits are forecasting a close game. Here is an early overview of the matchup.

Three "X" Factors

1. Super Bowl experience

The Steelers, only two years removed from winning Super Bowl XLIII, have an edge in experience that will come in to play both on and off the field. Having been in four Super Bowls myself, here is how I see the edge manifesting itself:

There are a lot of off the field distractions the players and staff have to deal with. These include ticket requests, media requests, family and friends travel, etc. The coaches have to manage these distractions while determining how much of the game plan to install at home and how much to install after arriving in Dallas. Some teams like to put in the game plan before they get to the Super Bowl site in order to have it done before the majority of distractions set in. Others want to wait so as not to have the players get bored or stale the week of the game.

The Steelers and their staff have dealt with this conundrum before. The Packers, for the most part, have not.

2. The two weeks to prepare and rest

I think this could favor or hurt Green Bay – we won't know until the game. On the one hand Green Bay is on a roll. They have faced elimination in their last five outings. They survived and, thus, have momentum. The two-week break could disrupt that momentum.

On the other hand, the break may be just the thing they need to get recharged. If they had to play next week, they maybe would run out of gas.

3. Green Bay’s familiarity with defensive scheme

The Packers may have an edge over many, if not all, of the opponents that the Steelers have played this year. That edge? They play the same 3-4 defense as Pittsburgh. Packers defensive coordinator Dom Capers and Steelers defensive coordinator Dick LeBeau worked together in Pittsburgh when LeBeau was the defensive backs coach when Capers was the defensive coordinator (1992-94). This will help Green Bay more than other teams that have had to prepare for Pittsburgh this season, as Green Bay will have had a better look in practice from their scout team in imitating Pittsburgh's defense.

Two key statistical categories that could come into play

1. Sacks per pass play

In terms of sacks per pass play, the Steelers offense ranks 30th in preventing sacks, while the Packers defense ranks third. On the other side of the ball, Green Bay's offense is 20th in sacks per pass play while Pittsburgh’s defense is sixth. Just watching film, it would seem Green Bay has the edge here. The statistics agree.

Both teams will have the opportunity to sack the opposing QB. I believe it comes down to which QB can avoid the pressure and still make a play. Conversely, which team when they get that free defender can bring the opposing QB down? Ben Roethlisberger is not only mobile, he is big and strong. He can throw with defenders draping off of him. Aaron Rodgers, on the other hand, is quicker a foot than Roethlisberger and can avoid defenders.

2. Rushing

The Steelers run defense is ranked number one in the NFL. The Packers rushing offense is ranked 24th. This is a clear advantage for the Steelers. How will the Packers be able to run the ball? I believe their best chance will be to spread the Steelers out to make them defend the pass first, then come back with the run second. In other words, set up the run with the pass.

Three matchups of note (Green Bay offense vs. Pittsburgh defense)

1. Green Bay Wide Receivers vs. Pittsburgh CB's

The Packers have a decided edge here. The two things the Steelers must do to negate this edge is a.) jam the receivers off the line to disrupt their timing on their routes in their rhythm passing game and b.) do a good job tackling when Green Bay’s wideouts catch the ball. Greg Jennings, Donald Driver, James Jones and Jordy Nelson are all fantastic at running after the catch.

2. Green Bay's OT’s vs. Pittsburgh’s OLB’s

This is an edge for Pittsburgh. Most defenses only have one good pass-rusher. Pittsburgh has two in James Harrison and LaMarr Woodley. Green Bay has to either make sure they help their OT's in some way (likely with a RB chipping or a TE staying in to block). The Packers cannot let the Steeler OLB's go one on one against Chad Clifton, Bryan Bulaga, backup T.J. Lang or one of their backs.

This is an advantage for Pittsburgh in terms of size and strength. If the Packers can't find a way to control Hampton by helping Wells or devise a running scheme to take advantage of Hampton's tendency to over-pursue (such as having the RB cut back against the grain in the opposite direction of Hampton's initial movement), they will struggle to run the ball.

Raji will have a decided edge over whoever Pittsburgh plays at OC (Pro Bowl rookie Maurkice Pouncey hopes to play on his bad ankle; third-year pro Doug Legursky is the backup). It is the same principle that Green Bay faces in running the ball against Casey Hampton: you need a plan to negate the edge that the opposing NT has over your C.

2. Green Bay’s nickel defense vs. Pittsburgh’s run offense

Green Bay will line up in their nickel defense on running downs and dare teams to run the ball. (Often times, they have just two defensive linemen in these packages.) If the Packers do this, the Steelers have to take advantage and run the ball effectively.

Both OT's for Pittsburgh, Scott and Adams, are backup players. Mathews, like James Harrison, is one of the best pass-rushers in the NFL. Mathews has to win his matchups against the Steelers tackles. The Packers do a good job moving him around to get him into favorable matchups. Can the Steelers figure this out and find a way to block him?

Beyond the statistics and matchups: two more things to watch

1. Will Green Bay employ a strategy similar to New England's plan against the Steeler defense? The Patriots spread the Steeler defense out and had a lot of success passing the ball. I think that is the best plan to beat the Steeler defense – and I think the Packers have the ideal personnel to execute that plan.

2. Will the Steelers try to run the ball to the outside early in the game to make those big Packer defensive linemen run to the ball? The hope here is that doing so will make those D-linemen tire and wear down as the game goes along. Fatigued defensive linemen, of course, are less effective against both the run and pass later in the game.

Prediction

This is a very even game, but I give the edge to the Steelers because of the slight edge at QB and their greater big game experience. I think the difference in the game will be Roethlisberger making more plays against the pass-rush than Rodgers.
